Sorry I didnt get back to this sooner...didnt turn on notifications.
Here is the kicker....The left side has a busted housing mount when she took out a fence post two winters ago. That one rattles some and the housing is loose but that one works fine. The right side is not damaged at all. No moisture inside the housing, (one of the first things I thought it was), nuttin. I am beginning to hate this thing. Already gone through another bulb.
